I haven't run over 90 since I was a teenager since my wrists can't handle it, but I won't run less than 70-80. Put 80 in plenty of 65psi tires without ever having an issue. Tires are always slightly underrated.
Like how I run 55-60PSI in car tires on the back of my drift car, when car tires are only rated to 44psi normally. Just gotta make sure you have the high pressure valve stems.
